I've tried an xserver-1.16, and ddx, libdrm without LTO and with gcc4.9. Exactly the same thing. I wondered whether the unused i810 could be interfering but triggering a device "remove" before starting X made no difference.
I'm a bit of a loss. I suppose I could try writing a simple test for drmSetInterfaceVersion(). At least that should determine whether the xserver/ddx is in the clear.
Any other ideas?
Can you start a non-X runlevel and start X manually as root (assuming you are using a login manager now)?
I've written a simple test based on the code from radeon_kms.c
I just need to try it on the actual hw now... :-)
